No, we're pretty sure you're wrong there, probably because you're 
purposely ignoring our *specific* characterization of the thing which
was actually done.

I disagreed with two statements:- 

On the engineering side, _impossible_.  Modern satellite
feeds of NTSC (analog) TV signals use compressed digital
representations of only the image portion of each 'field'
of the video stream

With my Captain Obvious hat on I said digital systems can carry such
data. The case where some cable companies interfere with the original
broadcasters data doesn't demonstrate it is impossible, they don't
affect the quoted satellite case nor others such as DTT

On the financial side, it is trivial.

I don't disagree with the cable cases quoted by others, they
demonstrate why I disagreed that it's financially trivial.

Of course I'm wrong, it is financially trivial as they would carry it
if you paid them. It's just highly unlikely to be financially viable

You can't really guarantee that random things injected into a transport
stream mux at the send end will make it to the receive end; everyone in
the transport path very likely thinks they're entitled to pull the 
separate program streams out and fiddle with them however they like --
Hell: local cablecos *reencode* the local station HD signals to compress
them further.

Yes, that was the case with analogue too, they just hadn't found
someone to sell the data to back then. Cable companies will mess with
anything including netflix.

In our case we sold VBI data so I coudln't make a viable case to offer
a USENET service.
